CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to and the benefit of U.S. Ser. No. 63/173,137 entitled “AIR FLOW SYSTEMS AND METHODS FOR HORTICULTURE SCAFFOLDING SYSTEMS” filed on Apr. 9, 2021 and incorporated herein by reference, including but not limited to those portions that specifically appear hereinafter, but except for any subject matter disclaimers or disavowals, and except to the extent that the incorporated material is inconsistent with the express disclosure herein, in which case the language in this disclosure shall control.

TECHNICAL FIELD

The present disclosure relates to air delivery, and in particular to air flow systems and methods utilized in connection with horticulture applications.

BACKGROUND

In order to obtain optimum growth, plants release water vapor into the air to be evaporated, allowing them to absorb the water found in the growing media. Moving the air and creating a current encourages this transpiration process. Additionally, plants require carbon dioxide (CO₂) to breathe and engage in photosynthesis. Poor airflow may result in a deficiency in CO₂, as well as other environmental issues affecting the plant canopy, so the plant cannot properly transpire and metabolize. Accordingly, improved air flow systems and methods, including for horticulture applications, remain desirable.

SUMMARY

In an exemplary embodiment, an air flow system, comprises a manifold, a fan coupled to the manifold, and a ventilation sock coupled to the manifold. In another exemplary embodiment, a scaffold system for horticulture comprises: a row of racks, and an air flow system coupled to the row of racks, the air flow system comprising a manifold, a fan, and a ventilation sock.

In another exemplary embodiment, a method for providing airflow to a plant comprises coupling a manifold of an airflow system to a horticulture rack, coupling a fan to the manifold, coupling a ventilation sock to the manifold, passing a metal wire through a series of loops on the ventilation sock to suspend the ventilation sock from the horticulture rack, and operating the fan to circulate air through the ventilation sock and deliver the air to plants disposed on the horticulture rack.

The foregoing features and elements can be combined in various combinations without exclusivity, unless expressly indicated otherwise. These features and elements as well as the operation thereof will become more apparent in light of the following description and the accompanying drawings. It should be understood, however, the following description and drawings are intended to be exemplary in nature and non-limiting.

Principles of the present disclosure may be compatible with and/or may be utilized in connection with principles disclosed in U.S. Ser. No. 16/802,036 filed on Feb. 2, 2020, now U.S. Pat. No. 11,304,525 entitled “Customizable Slidable Shelving and Support System for Horticulture Applications.” Additionally, principles of the present disclosure may be compatible with and/or may be utilized in connection with principles disclosed in U.S. Ser. No. 17/741,955 filed on Sep. 10, 2021, now U.S. Patent Application Publication No. 2022-0098881 entitled “Configurable Scaffolding System.” The disclosure of each of the foregoing applications is incorporated herein by reference in its entirety, including but not limited to those portions that specifically appear hereinafter, but except for any subject matter disclaimers or disavowals, and except to the extent that the incorporated material is inconsistent with the express disclosure herein, in which case the language in this disclosure shall control.

With reference now to FIG. 1, in various exemplary embodiments, a customizable horticulture racking system 100 comprises and/or may be coupled to or utilized with an air flow system 200. Although illustrated as being a part of customizable horticulture racking system 100, air flow system 200 is not limited in this regard. For example, any currently existing compatible shelving system or future developed compatible shelving systems may utilize air flow system 200 and are within the scope of this disclosure. In some exemplary embodiments, horticulture racking system comprises a system disclosed in U.S. Pat. No. 11,304,525.

The customizable horticulture racking system 100 may interface with and/or attach to or decouple from a scaffolding system (not shown). For example, an exemplary scaffolding system as disclosed in U.S. Patent Application Publication No. 2022-0098881 allows workers to safely access the various tiers of racking and service plants in horticulture racking system 100. Use of the scaffolding system eliminates the need to utilize a ladder, wheeled staircase, or scissor lift. Additionally, use of the scaffolding system allows access rows or aisles between vertical racks to be made narrower, leaving more space for racks and thus significantly improving the density of plants that are able to be grown in a particular space.

Horticulture racking system 100 may be formed from any suitable materials, for example aluminum, steel, high-strength plastics, and/or the like. Components may be machined, stamped, cast, and/or otherwise formed in any suitable manner or process. Additionally, components may be permanently and/or releasably coupled to one another and/or to other systems or devices via any suitable method, for example welding, brazing, and/or mechanical fasteners such as rivets, screws, bolts, and/or the like.

In various exemplary embodiments, horticulture racking system 100 comprises one or more each of a work deck, vertical upright brackets, decking brace, safety flag (fixed and/or telescoping) and a trim cover (fixed and/or telescoping). However, additional and/or fewer components may be utilized in certain embodiments, as suitable.

Referring now to FIG. 2, an exploded view of an exemplary air flow system 200 is illustrated, in accordance with various exemplary embodiments. The air flow system 200 is configured to provide enhanced air delivery to plants on various horticulture racking systems (e.g., horticulture racking system 100 from FIG. 1, or the like). The air flow system 200 may be configured to be coupled, or mounted, to a row of racks, such as a front row of racks or back row of racks, in accordance with various exemplary embodiments. In this regard, the air flow system 200 may include a manifold 210 configured to mount to the respective row of racks, in accordance with various exemplary embodiments. The manifold 210 may be mounted to a row of racks by any suitable means, such as mechanical fasteners (i.e., rivets, screws, bolts, and/or the like). In various embodiments, manifold 210 may be integral with a respective rack. In various embodiments, the manifold 210 comprises an inlet port 212 and a plurality of outlet ports 214.

In various embodiments, the air flow system 200 may further comprise ventilation socks 220. The manifold 210 is configured to be in fluid communication with the ventilation socks 220. In various embodiments, the ventilation socks 220 are made of a fabric or other thin material, or any other suitable material having a desired amount of porosity. In some exemplary embodiments, the sock material comprises one or more of nylon, polyester, vinyl, acrylonitrile butadiene styrene (ABS) plastic, etc. In this regard, an exit velocity of an airflow through the porosity of the sock material from the air flow system 200 may be varied by reconfiguring the air flow system 200 with another ventilation sock having a differing porosity, in accordance with various exemplary embodiments. Similarly, a porosity of the sock material may vary along a length of the row based on a respective design intent of the air flow system 200. Thus, in accordance with various embodiments, outlet velocity for the air flow system 200 may be customizable and/or reconfigurable. In various embodiments, the sock material may be rigid, or semi-rigid when not in use (i.e., when air is not flowing through it). In various embodiments, the sock material may be non-rigid when not in use and/or may be supported by brackets, clamps, braces, retaining loops, and/or the like.

In various embodiments, the ventilation socks 220 may further comprise a plurality of outlet apertures 222 spaced apart axially along a length of a row. In various embodiments, an outlet pattern may be equally spaced or include varying spacing. In various embodiments, the plurality of outlet apertures 222 may be in addition to a porous material or replace a porous material for the ventilation socks 220. In this regard, ventilation socks 220 may be made of more rigid material, such as a polymeric material (i.e., polyvinyl chloride (PVC)), a natural rubber, a synthetic rubber, a silicone, an elastomer, a thermoplastic, a thermoset, or the like. In various embodiments, variable spacing may be provided for horticulture applications where one area along a row of plants is denser than an adjacent area along a row of plants, or where one area has a plant with differing desired air flow relative to an adjacent plant. Thus, the air flow system 200 may be adaptable to various applications, in accordance with various embodiments.

In various embodiments, the inlet port 212 of the manifold 210 is configured to receive an in-line fan adapter 230. In this regard, an inlet flow may be controlled by reconfiguring the air flow system 200 with various in-line fan adaptors and/or various fans in order to input a desired air flow into the inlet port 212 of the manifold 210. The air flow system 200 may further be customizable and/or reconfigurable by adjusting or adapting an air flow input via a respective in-line fan adapter 230, in accordance with various embodiments. Although the in-line fan adapter 230 is configured to receive two fans therein, the present disclosure is not limited in this regard. For example, the in-line fan adapter 230 may be swappable for an in-line adapter configured to receive a single fan and/or an in-line adapter configured to receive more than two fans, in accordance with various embodiments. Similarly, in various embodiments, in-line adapter 230 may be utilized with a single fan (i.e., a fan in communication with inlet port 232 of in-line fan adapter 232) and a seal for the adjacent inlet (i.e., a seal for the inlet port 234 of the in-line fan adapter 234).

Similar to the inlet port 212 of the manifold 210, the plurality of outlet ports 214 of the manifold 210 may provide similar flexibility and adaptability to the air flow system 200. For example, the air flow system 200 may further comprise ventilation sock adapters 240 and/or exhaust restrictor plates 250. Thus, if only a single ventilation sock (e.g., ventilation sock 220) is desired, a single ventilation sock adapter (e.g., ventilation sock adapter 240) may be coupled to an outlet port in the plurality of outlet ports 214, and a remainder of outlet ports in the plurality of outlet ports 214 may have an exhaust restrictor plate (e.g., exhaust restrictor plate 250) coupled thereto, in accordance with various exemplary embodiments. The exhaust restrictor plate 250 and the ventilation sock adapter 240 may be mounted/coupled to a respective outlet port in the plurality of outlet ports 214 by any suitable means, such as via mechanical fasteners (i.e., rivets, screws, bolts, and/or the like), press-fit, adhesive, clamps, etc.

In various embodiments, ventilation socks 220 are configured to couple to the ventilation sock adapters 240 as described previously herein. Similarly, a respective fan is configured to be coupled to a respective inlet port (e.g., inlet port 232 or inlet port 234) of the in-line fan adapter 230 by any method previously described herein.

Referring now to FIG. 3, a perspective view of an air flow system 200 is illustrated in an assembled state, in accordance with various exemplary embodiments. In various embodiments, the air flow system 200 further comprises a fan 310 coupled to the inlet port 232 of the in-line fan adapter 230 from FIG. 2. Similarly, the air flow system 200 may further comprise a fan 320 coupled to the inlet port 234 of the in-line fan adapter 230. As described previously herein, any suitable number of fans is within the scope of this disclosure. The fans 310, 320 may be any suitable fan, such as an electrical fan, an axial flow fan, a centrifugal fan, etc.

The fans 310, 320 may be in fluid communication with the plurality of outlet ports 214 of the manifold 210 from FIG. 2, in accordance with various exemplary embodiments. For example, as shown in FIG. 4, inlet port 232 and inlet port 234 of the in-line fan adapter 230 may be in fluid communication with each outlet port in the plurality of outlet ports 214 of the manifold 210, in accordance with various embodiments. Although illustrated in this manner, the present disclosure is not limited in this regard. For example, the inlet port 232 may be in fluid communication with a first set of outlet ports in the plurality of outlet ports 214 of the manifold and the inlet port 234 may be in fluid communication with a second set of outlet ports in the plurality of outlet ports 214, the first set of outlet ports and the second set of outlet ports being mutually exclusive, in accordance with various exemplary embodiments.

In various embodiments the air flow system 200 described herein may provide enhanced air filtration, humidity control/injection, CO₂ control/injection, and/or UV-A, UV-B, and/or UV-C sterilization. In various embodiments, the air flow system 200 described herein is customizable, adaptable, and/or reconfigurable based on specific applications.

With reference now to FIG. 5, in various exemplary embodiments, the customizable horticulture racking system 100, as described herein, comprises and/or may be coupled to or utilized with an air flow system 300. The distance from a floor to the bottom of the air flow system 300 may be approximately 52 inches. In various embodiments, more than one air flow system 300 may be used. For instance, the distance between each air flow system 300 may be approximately 2.5 inches. Moreover, although illustrated as being a part of customizable horticulture racking system 100, air flow system 300 is not limited in this regard. For example, any currently existing suitable shelving system or future developed suitable shelving systems may utilize air flow system 300 and are within the scope of this disclosure.

Referring now to FIG. 6, an exploded view of the air flow system 300 is illustrated, in accordance with various exemplary embodiments. The air flow system 300 is configured to provide enhanced air delivery to plants on various horticulture racking systems (e.g., horticulture racking system 100 from FIGS. 1 and 5, or the like). The air flow system 300 may be configured to be coupled, or mounted, to a row of racks, such as a front row of racks or back row of racks, in accordance with various exemplary embodiments. In this regard, the air flow system 300 may include a manifold 310 configured to mount to the respective row of racks, in accordance with various exemplary embodiments. The manifold 310 may be mounted to a row of racks by any suitable means, such as mechanical fasteners (i.e., rivets, screws, bolts, clamps, and/or the like). In various embodiments, manifold 310 may be integral with a respective rack. In various embodiments, the manifold 310 comprises an inlet port 312 and a plurality of outlet ports 314. A perspective view of an exemplary manifold 310 is illustrated in FIG. 9. The inlet port 312 of the manifold 310 may have an inner diameter of 306 millimeters. The plurality of outlet ports 314 of the manifold 310 may have diameter of 134-136 millimeters.

In various embodiments, the air flow system 300 may further comprise ventilation socks 320. The manifold 310 is configured to be in fluid communication with the ventilation socks 320. For instance, the ventilation socks 320 may be coupled to the plurality of outlet ports 314 of the manifold 310. In various embodiments, the ventilation socks 320 are made of a fabric, or any other suitable thin material having a desired amount of porosity. In some exemplary embodiments, the sock material comprises one or more of coated paper, nylon, polyester, vinyl, acrylonitrile butadiene styrene (ABS) plastic, etc. In this regard, an exit velocity of an airflow through the porosity of the sock material from the air flow system 300 may be varied by reconfiguring the air flow system 300 with another ventilation sock having a differing porosity material, in accordance with various exemplary embodiments. Similarly, a porosity of the sock material may vary along a length of the row based on a respective design intent of the air flow system 300. Thus, in accordance with various embodiments, outlet velocity for the air flow system 300 may be customizable and/or reconfigurable. In various embodiments, the sock material may be rigid, or semi-rigid when not in use (i.e., when air is not flowing through it). In various embodiments, the sock material may be non-rigid when not in use and/or may be supported by brackets, clamps, braces, retaining loops, and/or the like.

In various embodiments, the ventilation socks 320 may further comprise a plurality of outlet apertures 322 spaced apart axially along a length of a row. In various embodiments, an outlet pattern may be equally spaced or include varying spacing. In various embodiments, the plurality of outlet apertures 322 may be in addition to a porous material or replace a porous material for the ventilation socks 320. In this regard, ventilation socks 320 may be made of more rigid material, such as a polymeric material (i.e., polyvinyl chloride (PVC)), a natural rubber, a synthetic rubber, a silicone, an elastomer, a thermoplastic, a thermoset, or the like. In various embodiments, variable spacing may be provided for horticulture applications where one area along a row of plants is denser than an adjacent area along a row of plants, or where one area has a plant with differing desired air flow relative to an adjacent plant. For instance, as illustrated, there may be fourteen outlet apertures 322 on each ventilation sock 320. However, in various embodiments, there may be more or less outlet apertures 322 on each ventilation sock 320. The outlet apertures 322 may be of varying size. The size and spacing may depend on the distance from the manifold 130 and/or the length of the ventilation socks 320. Further, the outlet apertures 322, as illustrated, may be disposed on a top surface (e.g., at “12 o'clock”) or may be disposed on a bottom surface (e.g., at “6 o'clock”). In various embodiments, the outlet apertures 322 may be in a straight line across the top surface and/or may be disposed in multiple sets of outlet apertures 322 at various angles along the surface of the ventilation socks 320. Thus, the air flow system 300 may be adaptable to various applications, in accordance with various embodiments

In various exemplary embodiments, ventilation socks 320 may be supported by and/or suspended along their length, for example by a metal wire rope of about 2-3 mm diameter passing through a series of loops spaced at intervals on the top of a ventilation sock 320. For instance, referring to FIG. 10, ventilation socks 320 may be supported by metal wire rope 328. The metal wire rope 328 may be threaded through a series of wire loops 330 in order to keep the wire in line and provide support across the length of the ventilation sock 320. The metal wire rope 328 may be tensioned, for example by coupling to a turnbuckle 332, in order to suspend ventilation sock 320 in a desired orientation. The turnbuckle 332 may be used to adjust/accommodate for small changes in the length of the horticulture racking 100. Additionally, the metal wire rope 328 may be coupled and decoupled from horticulture racking 100, for example by connecting/disconnecting the turnbuckles 332, in order to allow for quick and simple replacement of a ventilation sock 320. Moreover, ventilation sock 320 may pass through a series of loops hanging below a horticulture shelf in order to support ventilation sock 320.

Ventilation sock 320 may be sized as desired. In an exemplary embodiment, ventilation sock 320 has dimensions of about 140 mm in diameter and a length of about 10 meters. In another exemplary embodiment, ventilation sock 320 has dimensions of about 140 mm in diameter and a length of about 7.44 meters. In yet another exemplary embodiment, ventilation sock 320 has dimensions of about 140 mm in diameter and a length of about 15 meters. In various exemplary embodiments, the ventilation socks 320 may be manufactured in lengths between 7-10 meters and may be configured to be coupled together to accommodate for longer duct length requirements. Alternatively, the ventilation socks 320 may be configured to be cut for a shorter duct requirement. The ventilation socks 320 may be differing diameter, thickness, or material depending on the application.

The air flow system 300 includes a manifold bracket 324. The manifold bracket 324 is configured to couple with the manifold 310. The manifold bracket 324 may have a length of 1-2 meters, a height of 20 millimeters, and a thickness of 25 millimeters. The manifold bracket 324 may be manufactured with cold rolled steel. Further, the manifold bracket 324 is configured to couple with the customizable horticulture racking system 100. As such, the manifold bracket 324 facilitates coupling between the manifold 310 and the customizable horticulture racking system 100. Diagonal adapters may further be included and configured to further support the manifold 310. Particularly, the diagonal adapters may be disposed adjacent to where the manifold bracket 324 couples with the customizable horticulture racking system 100.

The air flow system 300 further includes an end cap assembly 330. The end cap assembly 330 comprises a cap bracket 332 and a plurality of duct caps 334. The plurality of duct caps 334 are configured to couple with the ventilation socks 320. For instance, the plurality of duct caps 334 are configured to cap the ventilation socks 320 at ends of the ventilations socks 320, the end being opposite the manifold 130. The duct caps 334 may have an outer diameter of 130-150 mm, corresponding with the diameter of the ventilation socks 320. The duct caps 334 may have a length of 128 mm and a thickness of 3 mm. The cap bracket 332 is configured to couple with the plurality of duct caps 334. The cap bracket 332 is configured to couple with the customizable horticulture racking system 100. As such, the cap bracket 332 facilitates coupling between the air flow system 300 and the customizable horticulture racking system 100. Additionally, end cap assembly can provide stability and support to ventilation socks 320. A perspective view of the end cap assembly 330 is illustrated in FIG. 8.

Referring now to FIG. 7, a perspective view of an air flow system 300 is illustrated in an assembled state, in accordance with various exemplary embodiments. In various embodiments, the air flow system 300 further comprises a fan 410 coupled to the inlet port 312. The fan 410 may be any suitable fan, such as an electrical fan, an axial flow fan, a centrifugal fan, etc. For instance, the fan 410 may be a 12″ standard fan. In contrast with the embodiment described with reference to FIGS. 2-4 (e.g., the air flow system 200), the air flow system 300 does not require an in-line fan adapter. Similarly, in various exemplary embodiments air flow system 300 does not comprise ventilation sock adapters and/or exhaust restrictor plates, as described previously herein with respect to air flow system 200. Accordingly, the manifold 310 is configured to attach directly to the fan 410, as well as directly to the ventilation socks 320 (e.g., fabric ducts).

The fan 410 may be in fluid communication with the plurality of outlet ports 314 of the manifold 310, in accordance with various exemplary embodiments. For example, as shown in FIG. 7, inlet port 312 may be in fluid communication with each outlet port in the plurality of outlet ports 314 of the manifold 310, in accordance with various embodiments.

The air flow system 300 includes a fan bracket 326. The fan bracket 326 is configured to couple with the fan 410. For instance, the fan bracket 326 may include side brackets configured to be in confronting relation with the sides of the fan 410 such that the fan 410 is supported by the fan bracket 426. The fan bracket 326 may have a length of 1-2 meters, a height of 80 millimeters, and a thickness of 20 millimeters. The fan bracket 326 may be a carbon steel rectangular tube. Further, the fan bracket 326 is configured to couple with the customizable horticulture racking system 100. As such, the fan bracket 326 facilitates coupling between the fan 410 and the customizable horticulture racking system 100.

In various embodiments described herein, the ventilation socks 320 are configured to be disposed between a horticulture rack and a grow light. In other various embodiments, an air flow system is mounted on a tray of the horticulture rack with ducts (e.g., ventilation socks) blowing up through a canopy of plants into grow lights. Additionally, in various embodiments, an exemplary air flow system may include an airflow return. In such a configuration, ducts (e.g., ventilation socks) may be disposed above the grow lights and configured to blow down through the plants, where the airflow is sucked into an airflow return disposed generally at the level of the tray. In this manner, air may be circulated to plants and then returned for further processing, filtration, and/or recirculation. Moreover, in various exemplary embodiments, an air flow system may provide both ventilation sock(s) and airflow return(s) in such a manner that (i) supplied air flows generally upward from ventilation socks, across plants, and into airflow returns, or (ii) supplied air flows generally upward from ventilation socks, across plants, and into airflow returns.

In various embodiments the air flow system 300 described herein may provide enhanced air filtration, humidity control/injection, CO₂ control/injection, and/or UV-A, UV-B, and/or UV-C sterilization. In various embodiments, the air flow system 300 described herein is customizable, adaptable, and/or reconfigurable based on specific applications.
